7,4, ATTORNEYS Patented Mar. 31, 1931 UNITED STATES JAMES H. WAGENHOBST, OF DETROIT, MICHIGAN AUTOMOBILE WHEEL RIM Application filed June 4, 1929/ Serial No. 368,388.

My invention relates to improvements in automobile wheel rims and has to do, more particularly, with rims of the q. d. type, which have a detachable side flange.

5 On account of the high speeds at which the modern automobile is operated, suflicient centrifugal force is generated to displace the detachable tire-retaining flange from the gutter in which it is seated, when the tire is re deflated, unless some locking means are provided to prevent this. The object of my invention is to provide simple, effective and inexpensive means to prevent inadvertent displacement of the detachable tire-retaining flange.

Further objects, and objects relating to details and economies of construction and operation, will definitely appear from the detailed description to follow. In one instance, I accomplish the objects of iny'invention by the devices and means described in the annexed specification. My invention is clearly defined and pointed out in the appended claims. A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a fragmentary view, partly in side elevation and partly in section, of a rim embodying my invention.

Fig. 2 is a transverse, sectional View taken on line 2-2 of Fig. 1,

Fig. 3 is a. transverse, sectional view taken on line 33 of Fig. 1,

Fig. 4 is a fragmentary perspective view of those portions of the detachable tire-retaining flange adjacent the split therein, and

Fig. 5 is a fragmentary view corresponding to a part of Fig. 3 but showing a slight modification.

In the drawings, the same reference numerals refer to the same parts throughout the several views.

Referring to the numbered parts of the drawing, my improved rim comprises the usual rim base having, at one side, a the retaining flange 11 and, at the other side, a radially inwardly-extending gutter 12 having front and rear walls, 14 and 13, and a bottom wall 15. The gutter walls 13 and 14 seats in the gutter and is obliquely inclined Ear.

to correspond with the inclination of the gutter walls. This detachable flange ring is split at 18.

A pair of pins, 23 and 24, are inserted through and secured to the gutter walls and span the gutter, as shown in Fig. 2. These pins cooperate with notches in the base of the removable flange ring to prevent its accidental displacement. A circumferentiallyextending notch 19 is formed in one end of the flange ring base and receives the pin 23. Adjacent the notch 19, in the same end of the ring, there is formed a radial notch 20, receiving the pin 24. The Wallet notch 20 nearest notch 19 is beveled as at 21. two notches together form a locking tongue 22in the base of the ring, at one end thereof, which co-acts with the pins 23 and 24 to prevent displacement of that end of the ring from the gutter, except by a preliminary swingingmovement thereof about pin 23.

An elongate-d hole 25 is formed through the opposite end portion of the detachable flange ring and a cotter pin 26 is inserted through holes in the gutter walls and hole 25, and the ends bent over against the rear gutter wall, as at 27. WVhen this cotter pin is in place it prevents radial displacement of this end of the flange ring. Instead of the cotter pin 26, a small bolt 28 may be used (see Fig. 5) which passes through a hole in the front wall of the gutter, through hole 25, and screws into the rear gutter wall.

The hole 25 is elongated and partly exposed These above the front gutter wall so that a tool may be inserted therein to pry the flange ring from its seat in the gutter, after the removal of cotter pin 26. 1

The pin 23 engages the walls of notch 19 to prevent radial displacement of the correspending end of the flange ring. Circumferential displacement of the ring, such as would free pin 23 from notch 19, is prevented by the engagement of pin 24 withthe walls of notch '20. It will be seen, however, that, by swinging the end of the ring about pin 23 as a center, notch 20 will clear pin 24 and the ring can then be moved longitudinally away from pin 23. Such a movement is impossible under normal conditions, however, because the pin 26 prevents radial displacement of the opposite end of the flange ring. I have provided, therefore, very simple, light and inexpensive means for preventing accidental displacement of the flange ring. When the tire is deflated and the ring is to be removed, the cotter pin 26 is, first, withdrawn and that end ofthe ring is pried from its seat in the gutter. Vol-king from that end, the ring can be progressively removed from its seat and, finally, the opposite end is turned about the pin 23, until notch 20 clears pin 24:, and then pulled away from pin 23, thus, completely freeing the ring.

I am aware that the structure here shown may be changed considerably, without departing from the spirit of my invention, and, therefore, I claim my invention broadly, as indicated by the appended claims.

What I claim is:

1. A tire-carrying rim comprising the combination of a rim base having a tire-retaining flange at one side and a radially inward- ].y-extending gutter at the other side thereof, a retaining pin fixed to the side walls and spaced from the bottom of said gutter, a transversely-split detachable tireretaining flange seated in said gutter and having a circumferentially-extending notch in one end for receiving said pin, means adjacent said notch and pin for maintaining their association and detachable means for preventing radial movement of the opposite end of the split flange.

2. A tire-carrying rim comprising the combination of a rim base having a tire-retaining flange at one side and a gutter at the other side thereof, a pair of pins, spanning said gutter and fastened at their ends to the gutter walls with their intermediate portions spaced from the bottom of said gutter, and a transversely-split, detachable tile-retaining flange seated in said gutter and having a circumferentially extending notch in one end receiving one of said pins and an adjacent radial notch receiving the other of said pins, the wall of said last named notch adjacent the first-named notch having its wall nearest the circumferential not-ch inclined in such relation that the pin in the radial not-ch Will bear upon said inclined wall and force the circumferential notch into association with its pin.

3. A tire-carrying rim comprising the combination of a rim base having a tire-retaining flange at one side and a gutter at the other side thereof, a pair of pins anchored at their ends in the walls of and spanning said gutter, a transversely-split, detachable tire-retaining flange seated in said gutter and having a circumferentially extending notch in one end receiving one of said pins and an adjacent radial notch receiving the other of said pins, and detachable means for preventing radial movement of the opposite end of said flange.

4. A tire-carrying rim comprising a rim base having a tire-retaining flange at one side and a gutter at the other side thereof, a pair of pins fixed to the side Walls of and spaced from the bottom of said gutter, a detachable, transversely-split tire-retaining flange seated in said gutter and having a looking tongue at one end thereof cooperating with said pins to prevent displacement of said end of the flange from the gutter except by a preliminary swinging movement of said-end about one of said pins, and detachable means preventing radial displacement of the opposite end of said flange.

5. A tire-carrying rim comprising the combination of a rim base having a tire-retaining flange at one side and a gutter at the other side thereof, a transversely split, detachable tire-retaining flange seated in said gutter and having an elongated hole therein near one end thereof, and a pin detachably inserted through the gutter walls and said hole and preventing radial displacement of said end of the flange, said hole being partly exposed above the front wall of the gutter whereby a tool may be inserted therein to pry the flange from its seat.

6. A tire-carrying rim comprising the combination of a rim base having a tire-retaining flange at one side and a radially inwardlyextending gutter at the other side thereof, a pin spanning said gutter, spaced from the bottom thereof, and fastened at its ends to the side walls thereof, a transversely split detachable tire-retaining flange seated in said gutter and having in one end a circumferentially extending notch engaged with the intermediate portion of said pin, and detachable means maintaining the other end of the flange insaid gutter.
